UNITED STATES PATENT OFFICE,

LOUIS EMILE DUBOIS, OF TORONTO, ONTARIO, CANADA.

LOOM.

CPECIPICATIQII forming part of Letters Patent No. 367,028, dated July26, 1887.

Application filed January 1 1, 1887. Serial No. 224,340. (No model.)

To all whom it may concern.-

Be it known that I, Louis EMILE Donors, of the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, manufae turer,haveinvented certain new and useful Improvements in Looms, of which thefollowing is a specification.

The object of the invention is to provide aloom in which small feathersor small pieces of fur may be woven into a continuous web having a closebut flexible back; and it consistsin the peculiar combinations and thenovel construction, arrangement, and adaptation ofparts, allasmorefullyhereinafterdescribed and claimed.

Figure 1 is a perspective rear View of my loom with a portion of itsframe broken away, so as to exhibit more clearly my improvements. Fig. 2is a sectional side elevation.

In the drawings like letters ot' reference in- "dicate correspondingparts in each figure.

A is the main frame of the loom, substair tially constructed anddesigned to support the working parts.

In my loom I employ three heald-frames, marked, respectively, B, O, andI), the main warp-threads 11 passing through the loops in the healds aand I), while the supplemental warp-threads 6 pass through the loops inthe healds c. The warp-threads d are carried on the roller E, which issupported in suitable hearings on the posts F, a pin, f, being insertedinto one of the holes, 9, made in the roller E for the purpose ofpreventing the said roller revolving when it is desired to hold thethreads (I taut. The threads 0 are carried on the roller G, eachseparate thread being independently wound within a separate divisionformed on the said roller G, which roller is suitably journaled and heldby friction sufliciently to prevent it revolving except when drawn uponby the threads 6 as they require fresh length. This may be accomplishedin various ways. In the drawings I have shown an eyebolt, a, through theeye of which the shaft of the roller G is passed. This bolt is passedthrough a standard, F, and is provided upon its threaded end with athumb-nut, b, by tightening which the shaft of said roller may be causedto bind against said standard, more or less, as may be desired.

The heald-frames B, C, and D are supported by chains or cords H, whichpass over rollers journaled in blocks I,which are supported, asindicated, from the frame A.

In order that the heald-frames may balance each other and also becapable of operating to accomplish the purpose of my invention, Iconnect the heald-frame B to the heald-frame D, and to balance theheald-frame O, I provide an open frame, J, which is connected, as shown,to the heald-frame 0.

Four levers, K, L, M, and N, are connected, respectively, by the chainsor cords O to the respective frames B, O, D, and J. These levers K, L,M, and N are pivoted on theframe A, and are connected by the chains orcords I to the levers Q, which are pivoted at right angles to the leversK, L, M, and N, either upon the lloor or to the frame A. The free end ofeach of the levers Q is connected, respectively, to the treadles It, S,T, and U, by pins in each lever Q fitting into slots madein itsrespective treadle. From this it will be seen that the treadle R isconnected to the heald-frame B, and the treadle T to the healdframe O,while the treadle S is connected to the heald-frame D and the treadle Uto the open frame J.

Having now described the general construction of my loom, a few wordswill suffice to ex plain its operation.

Having set myloom to commence work, I place the small pieces of'fur orsmall feathers upon the main warp-threads d, the supplementalwarp-threads 0 being at this time supported above the said fur orfeathers. I then operate the trcadles B and T, so as to cause thethreads carried by the heald a to lower past the supplemental threads 6,which are carried by the heald c,which latter threads are simultaneouslycaused to rise by the action of the treadle T. The shuttle withtheweftthread is then thrown through the shed in the ordinary way, andas much ordinary weaving may then be done as thought desirable. When Iwish the pieces of fur or small feathers to be woven very closelytogether, I use only one weft-thread before bringing the supplementalthreads 0 again into action for the purpose of adding a fresh piece offur or feathers, the

number of weft-threads beingincreased if it is desired to make the furlight and open.

It willof course be understood that the lay \V is operated as inordinary hand-looms.

What I claim as my invention is 1. The combination, with the block I andpulley carried thereby, of the heald-frames B D, 'cord'or chain H,passed over said pulley and connected with said frames, the levers K M,cords 0, connecting said levers and frames, the levers Q, treadles RS,and the cords P, connecting the levers K M and treadles, substantiallyas and for the purpose specified.

2. The combination, with the heald-framcs B D, cords connecting saidframes together, the healdframe Gand open frame J, cords (2011 meetingthem together, as described, of the levers K L M N, pivoted at one end,connections between said levers and frames, the levers Q r 5 andtreadles R S T U, jointed together at their adjacent ends, and the cordsor chains P, connectiug each alternate lever Q with each alternate oneof the said levers K L M N, substantially as described.
